Dual personality anime and manga characters come in many different forms, but as with many things, the cause of such forms is what ultimately is the most insightful into seeing why they act the way they do. Motivations, conflicts, and responses to what is sometimes just normal stimuli to other characters are more clearly seen when examining the cause of such things.
One cause of the dual nature of these characters is one that we are more familiar with in the real world. A dual or multiple personality can come about because of natural happenings or responses to the world around the character. Whether it be through a past event, a dark past with a different mindset, an object that brings back suppressed (and unwanted) desires, or something else, characters who have taken on more than one personality tend to do so because it is a "safe" response to those circumstances. The psychological trauma of events that may have happened to them or were supposed to shape them into one identity instead elicits a reaction of retaining or creating two or more personalities. In some cases, the character themselves was responsible for creating the trauma, and in order to deal with it, they create and most times suppress another personality within them. The transition between such personalities can either be subtle and slow, or quick.

The other major cause for a duality of personalities in anime characters stems from unnatural, or mythical causes. In most of these cases, the other personality is either forced or placed into their mind by outside circumstances. While it is artificial that for some of these characters that they are given another side of themselves, their other personalities still tend to cause just as much confusion and trauma as those that come into it naturally. Unlike natural duality, unnatural dual personality characters stand a somewhat better chance of being "cured" simply because of the fact that the cause of such duality is, for the most part, tangible, and removal results in an almost instant remedy. However, their personality shifts tend to come sudden and quick, and the fact that outside devices are the main factor in creating them make these characters more "efficient" in switching between personalities. This can make a remedy more difficult.

Whatever the cause, dual personality characters are a curious study and it is interesting to see how they relate to the story that is being written or told to the viewers or readers. Some may even focus on the duality of the character in question. Let's now pull out some specific examples and do a "case study" of some of the more prominent anime characters who experience this kind of personality.
Natural dual personalities are interesting studies in part becuase the depth of their duality usually goes back years and is usually fairly complex. Let's take a look at a couple of case studies to better understand the nature of this form of dual personality (NOTE: spoilers may follow, though I will try my best to talk in general terms).

As nice as it is to relate it to anime, there are real wold variations of the psychosis. As far as I know the most common variaty is Schitzophrenia; seeing things that arn't there, hearing voices in your head. Multiple personality Disorder is a deeper trauma than that, where there may actually be two (OR MORE!) personalities living in and controlling one body. I've heard of cases where the personalities don't know of each other, where one knows of the other, or where they both know of and can talk to each other. The trigger seems to be trauma, sometimes repressed memories that bundle together and form a personality to deal with stressful situations(ala Me, Myself and Irene), sometimes it's physical trauma to the brain itself( for movies I'd say Two-face is a prime example), and sometimes it's just stress (Fight Club).
I had previously thought trauma to the nervs connecting the right and left hemispheres of the brain could cause such a disorder, but I found that a tretement for severe epilepsy was to actually cut these fibers and bifurcate the brain! The results showed that the people's personalities remained the same (Tangent: I beleive they had difficulties reading with one eye and recognising faces with the other ater the operation.) so trauma to this area doesn't seem to incite MPD. I can't say I remember much about which areas of the brain cause MPD when damaged, but I do remember reading a few studies about it.

I'm hoping we have others who have a fresher memory of these things than me here. I can't be of too much help at the moment.

Mental illness is caused by wealth, comfort, and leisure. New Orleans was utterly destroyed. More than 300,000 of the lowest class were smashed into flooded streets and abandoned to die by their government. 10,000 of them were herded into the Superdome, huddled amidst growing tons of fresh human excrement as the roof poured water, the temperature and humidity rose, and they died.

Was anybody depressed? No, not a one. There is not a shred of evidence that anybody acted in any way other than sustained functional shining sanity. They won't start whining until the Liberals arrive. Then it will be wall-to-wall "chronic post-affective traumatic stress syndrome" for the rest of their freeloading lives. VICTIMS! "GIMME!"

I’m not a Psychiatrist, or even an MD, but I have a lot of experience with diagnostic coding systems, so on this subject I’m arguably an expert.

First, avoid a common misunderstanding of psychiatric terms: While the term “schizophrenia” comes directly from the Greek “schizo”=split and “phrenos”=mind, it refers not to a mind split into many separate personalities, but a mind that has become separated from the normal perception of reality. “Split personality” is not another term for schizophrenia.

A very small number of people suffer from a disorder most recently known as Dissociative Identity Disorder, formerly known as Multiple Personality Disorder, and, before that, “split personality”. How many people actually suffer from DID is the subject of much controversy. There’s broad consensus that the diagnosis is much over used. Prior to 1970, there were thought to have been fewer than ten documented cases of the disorder. Now, the most reasonable (in my opinion) consensus is that there are no more than a few hundred people alive with the disorder today.

Although no one really knows what causes it, common factors in the history of patients in whom the diagnosis seems most likely to be accurate usually involve severe childhood abuse, most often of a sexual nature, most often beginning around the onset of pubery. However, the vast majority of victims of such abuse do not develop DID, so other factors, possibly innate neurological ones, are likely to be involved.

Study of DID is complicated by widespread awareness of it. Many psychiatric patients claim to have it, but almost certainly do not, while many therapists believe that it is a common disorder, which it almost certainly is not.

Functional Magnetic Resonance Imaging (fMRI) and Positron Emission Therapy (PET) performed on a very few confirmed DID patients reveals startling and dramatic evidence that it is a profound disorder, not simply a behavior disorder. The separate personalities appear to use physically distinct regions of the brain. There is no data to indicate that this neurological activity can be exhibited by anyone other than true DID patients.

The Wikipedia entries for DID and schizophrenia have a good discussion of this very rare but interesting, and almost certainly real, disorder.

about 90 percent of multiple personality disorders are caused by severe abuse, in most cases during the early childhood because thats when we are still developing and havent yet learned other types of psychological defense mechanisms.

how exactly do psychologists define personality?
personality is a description of consistent emotional, thought, and behavior patterns in a person.

schitzophrenia would have to do with human psychological defense systems, enough abuse will cause your brain to try to block the current events (abuse) so eventually people create personalities that are not as much hurt by what is going on around them, by creating different sets of behaviors, emotions, thoughts, and science cant really explain everything just yet. and personalities dont always not know about each other, but most of the time for the other personalities it feels like a blackout. and personalities dont always have to be human, although they tend to be that most of the time, oh also they dont have to be of this world, so yes, there are people who have personalities such as dragons and gnomes and stuff

Someone try to took your own, or try to attache as a secondary without your permission,
(abuse)....So the person find himself in a situation, while feel as a different person, as well as act as a different person....

Split personality can be consciously induced. For example, most people have a work personna and a home personna. Often the two can not both exist optimumly at the same time. If one tries to combine them, they are often not as effective as one each specialized to its specific environment. But in both cases, each will take on a life of its own often with its own lingo, behavior, etc.. The student is often the knurd during the week and drunk during the weekends. The spelling of knurd was changed to nerd to help soften the suggestive affect of this forward-backward polarization..
